I created this for my freshman Preparing for College & Careers course. We attended a college fair and I wanted to keep them engaged and not just roaming around for free stuff. We had discussed the 16 National Career Clusters beforehand. In this activity they go to different colleges to find majors for different clusters. I actually had some of the college booths tell me that they loved the exercise because my students were actually talking with them and not just there to take pens.
Please see the the following link to help you and your students understand the 16 National Career Clusters.
